Abstract

A solid base catalyst for producing biodiesel is disclosed. A preparation method of the solid base catalyst comprises the following steps: providing a solid waste as a silica source, mixing and grinding the solid waste with a solid lithium compound to form a powder, and calcining the powder to obtain the solid base catalyst. The invention also provides a production method of the biodiesel using the solid base catalyst.

Description

technical field [0001] The present invention relates to a solid base catalyst, and in particular to a solid base catalyst for producing biodiesel. Background technique [0002] Fossil fuels are currently the bulk of energy used in the world. However, fossil fuels have many problems such as non-reusable, air pollution, small storage, difficult mining, and unstable prices. In contrast, biodiesel has the characteristics of biodegradability, non-toxicity, low gas pollution after combustion, and safe storage, and is regarded as one of the economical and potential energy alternatives. [0003] The production methods of biodiesel are mainly divided into chemical catalysis and biocatalysis. Among them, chemical base catalysis has the advantages of high transesterification rate and short reaction time, and is currently the most widely used technology. Catalysts used in chemical base catalysis include liquids and solids. Among them, solid base catalysts are more popular in the indust...
